ORNL microscopy uncovers "dancing" silicon atoms in graphene

(ASM International) Jumping silicon atoms are the stars of an atomic scale ballet featured in a new Nature Communications study from the Department of Energy's Oak Ridge National Laboratory, Oak Ridge, Tenn. The ORNL research team documented the atoms' unique behavior by first trapping groups of silicon atoms, known as clusters, in a single-atom-thick sheet of carbon called graphene...7/1

Lithium-Sulfur Battery Looks Promising For Electrified Vehicles

(Hybridcars.com) Could it be that the laboratory that once ushered in the atomic age has developed the battery chemistry that will enable affordable electric cars with 300-400 mile range? This is one implication for Oak Ridge National Laboratory‘s solid state nanotechnology based lithium-sulfur chemistry developed between 2007-2013. As we reported last month, ORNL announced it as a patent-pending scientific success that’s theoretically safer and cheaper than lithium-ion...7/1
